Vices… when seeking good goes bad

All the vices are distorted or excessive attachments to good things. Wrath is ostensibly born of concern for justice and honor, greed regards sufficient possessions, gluttony is about food, vainglory seeks the approval of others. Vice happens when our pursuit of these good things gets twisted, that is, when we try to make them fill gaps and needs in our hearts that only God can fill, and when we define happiness in terms of them, rather than appreciating them as (finite) blessings from God. — Rebecca Konyndyk DeYoung, Glittering Vices: A New Look at the Seven Deadly Sins and Their Remedies
